Programmable Radiator Mounted Heating Thermostat

Overview

Description

This thermostatic header for on a room heating radiator is an exceptionally universal albeit still compact solution.

System Benefits​:

  • MCU outputs data to an LCD segment display (lowest cost) or graphical matrix LCD
  • The GreenPAK™ programmable mixed-signal matrix enables the use of a brushed DC or stepper motor without any change in schematics/PCB and eliminates power transistors needs
  • The RL78 microcontroller device allows for easy expansion of the system with Bluetooth® Low Energy (LE) or Wi-Fi modules

Comparison

Applications

  • Thermostatic radiator-mounted controller with low-cost standalone motor
